Hello, I'm planing to buy a 2010 Megane RS 250 from some independent dealer. The car has around 68.000 miles on the dash. I drove already the car, but couldn't really push it, didn't have the place for it.

My question is, what should I check before buying. This is not a usual car and there is a possibility the previous owner abused it.

From my drive I notice that the steering is heavy when taking a corner, but I would expect its normal (I really dont know). Also noticed that the steering wheel its not exactly in the center when the wheels are strait, but that I mean, it seems to be on the left side by 2-3 degrees. I tried to do the start without the hands on the steering wheel and they don't seem to pull on left or right. The same I did for stop, from 20 mph, hands off the steering wheel and brake, and again didn't seem to pull left or right.

Another issue I saw is the tire pressure sensors on the right side of the car, were complaining, like it cant read or issue with the pressure, don't remember exactly.

Should I worry? The car is not that expensive and overall seems to drive nicely, but don't wanna spend and then need to spend more, at least for one or two years.

Also, off-topic, would CHIP tuning the engine to 260-270 bhp would decrease fuel consumption? I know that the 265 and 270 versions have been fuel economy.

Any tips or info would be greatly appreciated!

We didn't ask, as we just test drove the car. Lets say it doesn't, but it should.

Yes, but not in a language you can understand :)

So I called today and found out that it doesn't have a services history. Is that bad? Should I buy it?

Nor me. There must be some history at least. If not, I would avoid it

No service history means you can't verify what essential maintenance or repairs have been done, therefore you have no idea what needs to be done. As others have said, just the cam belt change will be a money pit.

If there's no official service history are there at least any receipts for repairs or maintenance carried out?
Admittedly it was a 16 year old car with 270,000km that I'd had repaired at a local garage for the last few years so they couldn't stamp the service booklet, but when I sold my previous Alfa it had receipts for all work done. This sometimes helps.

Ring a Renault Dealer up & ask!

Make sure you are sitting down tho!
