Hi Paul,

The manual gearbox on the E46-generation M3 is fine, as long as it’s not been abused and the car in general has been properly looked after. The SMG on the other hand is a nightmare of potential problems. Quite aside from being awkward and jerky to use even when it’s in perfect health, it develops frequent problems with the hydraulic pumps, solenoids and electrical relays. Avoid the SMG at all costs.

Hi Wayne,

Depends on the age and on the condition. The 1.5 dCi diesel is a pretty solid engine (look for turbo problems though) and if a Scenic is properly cared for and serviced on the button, they can be fine. Beware of electric gremlins on older cars and don’t buy anything that doesn’t come with a full service history.

Hi Eugene,

Lots. Mercedes was going through a major dip in build quality and reliability in the mid-2000s, and the electrical system, braking system and the gearbox are all deeply suspect. Make sure it comes with a fully-stamped-up service history and lots and lots of receipts for previous work done. Be suspicious of everything, and if you see any signs of excessive wear and tear, or of items that aren’t working properly, walk away. Also, make sure you do a history and background check with Cartell.ie and make sure it hasn’t been used as a taxi in the past.

Hi Jimmy,

Good or bad? 911? Depends on your expectations, but the 1981 911 - the SC, which ran from 1978 to 1983 - was a fine example of Porsche’s iconic model. Losing the slightly prettier, slimmer bumpers of the 1960-70s cars a 1981 911 will feature the ‘impact’ bumper as part of Porsche’s homologation for USA production. They still look fabulous, though; indeed, after a period looking a bit sketchy the nicest, unmodified 911s of this vintage look great, slim hipped, and in the right colour with all the contrasting black rubber trim pieces and period Fuchs or cookie-cutter alloys they’re lovely. Personally, I’d avoid the whale tail look, many having been fitted with them after the fact, but it’s an easy replacement if it comes so specified.

Interiors are robust, if slightly austere, though the large glasshouse and slim pillars make it a fine driving environment. Gearboxes are fine, the 3.0-litre engine solid too, though like any car that’s over 30 years old they’ll need a bit more fettling than a modern car. Thankfully it’s all largely mechanical (rather than electrical), so it can be maintained by a competent home mechanic, though if you’ve bought a great condition, properly serviced car it’s best to keep it that way. Performance will feel brisk rather than outrageous if you’ve been used to modern performance cars, but then the immediacy of the responses, feedback through the wheel et.c will be on a different level to anything newer.

Perhaps not a daily driver, but as a weekend toy it’s a good choice, which if looked after should be worth everything you paid for it, and more in time. Rust shouldn’t be an issue, as all these cars are galvanised, but do check the inner front and and rear wings, and fore of the rear wheels, any potential water traps around the doors, windows and engine/bonnet lid locks, the battery box and under the carpets inside. Bad rust will point to poor accident repairs. Take a good look underneath for oil leaks from both the engine and gearbox. 1981 cars deliver 204hp. Do a bit of internet digging; it’s an enthusiast car so there’s lots of info out there. If in doubt speak to a club/specialist and take them along for a viewing - they may charge but it could save you in the long run... Jealous? A bit, the 3.0 SC is a lovely thing...

Hi Chris,

Very economical — you should expect better than 50mpg. Reliable? Not so good — you should expect lots of electrical problems, and check the engine carefully for any turbo issues.

Hi Peter,

It certainly sounds like the alternator is not doing its job. Could you have disturbed the wiring from it when you fitted the fanbelt? Easiest way to check is to check the voltage across the battery terminals with a multi-meter while the engine is running. It should be well over 12V if it is charging.

Please be careful doing this though and only if you're confident working under the bonnet. If you're not, best leave a qualified mechanic or auto electrician have a look.

Hi Peter,

Nope, there appear to be no major issues with the Lacetti other than a tendency for water to get into the electrical system, causing some problems starting the car and with the alarm. It's not a complex problem, but it can take an age to find where the water is getting in so check and make sure that all the electrics are working properly on the car and if possible test drive on a wet, rainy day.

There have been some reports of Lacettis suffering from very high fuel consumption, but that could just be down to individual driving style.

Let us know if you'd like help finding an alternative.

Hi Ed,

Do you mean a Jaguar XF? The XK was the fast V8 coupe, and never had a diesel engine. If it is the XF, then they’re pretty solid cars. The diesel engine needs careful checking to make sure that the diesel particulate filter is working properly, and that the cam belt has been changed every 160,000km. Also listen for clonking suspension and check for cracked alloys, and make sure all the electrics are working properly. If it has a full service, then it should be fine.

As for the Merc, that generation of E-Class was very badly built, and you need to check and make sure that it’s been back in for all its ‘service recalls.’ Check for leaks from the transmission and the radiator, and the air mass sensor often triggers an engine warning light. Electronics are deeply suspect, and if the car vibrates under acceleration, the gearbox could need replacing.

Hi Geraldine,

Updated answer:

In 2015, Ford gave the Focus a major update, with new styling (check out that Aston-Martin-esque grille at the front) and an upgraded interior (new dials, fewer buttons and the option of the big, bright SYNC2 touch-screen system). The trim levels remained the same - Focus, Style, Zetec, Zetec + and Titanium with the range topped off by the sporting ST model.

Standard equipment on Focus models includes tyre pressure monitors, emergency brake assist, hill-holder clutch, 'MyKey' (which restricts speed, distance and stereo settings for the spare key - good if you have teenagers in the house), front electric windows, capless fuel filler, steering wheel stereo controls, height adjustable drivers' seat and split-folding rear seats.

Style adds a USB connection and Ford's SYNC connectivity for the stereo, manual air conditioning, body coloured door handles and power mirrors, 16-inch alloys, leather steering wheel and gear shifter and map pockets in the back of the seats.

Zetec models get front fog lights, lower, Sports suspension, a heated windscreen, sportier seats and an upgraded centre console.

Zetec + adds keyless start, drive lumbar support, 17-inch alloys, LED rear lights and a 'premium' centre console with a sliding arm-rest.

Titanium gets the same keyless start but adds dual-zone climate control, cruise control with speed limiter, all-round power windows, mesh radiators grille, an 'overhead console' with a sunglasses holder and integrated reading lights, velour upholstery, rear cup holders and ambient lighting.

ST models get all of that plus some extra sporty bits and seriously tweaked suspension and steering, while the current limited Black Edition and Red Edition come with manual air conditioning, curtain airbags, red stitching everywhere, scuff plates and exterior bodykit, acoustic windscreen and metallic pedal covers. 

Original answer:

Ford doesn't actually make an LX Focus any more. Instead, the basic Focus model is now just known as plain old Focus, and it comes with a CD player, USB connection, electric front windows and door mirrors, remote central locking, electronic stability control and, on the five-door hatch, a rear spoiler.

Next up is the Edge model, which adds air conditioning, a 3.5-inch colour display for the stereo, a leather steering wheel, heated mirrors, trip computer with economy driving monitor and body coloured door handles. Then there's the Zetec, which, over and above the Edge gets 16-inch alloy wheels, Quickclear windscreen, centre arm rest with stowage box and 12v plug, sports suspension and sportier front seats.

The Titanium takes all that and also gives you split-zone climate control, a start/stop button, cruise control, jazzier wheels (still 16-inch in diameter though), hill start assist, LED rear lights, aluminium scuff plates, footwell lights, a rear arm rest and a leather gear knob. Please bear in mind that these are current Focus model trims, and if you're looking at older models then they will be different.

Hi Angela,

Clearly any such warning needs to be taken very seriously and we'd recommend not driving the car until it is fixed.

We do know, however, that the Stilo regularly suffers from damaged wiring under the driver's seat that can lead to such issues. It could be as simple as a single wire that needs replacing. Bring the car to a mechanic or auto electrician and suggest that.
