I would say they a little over priced but lower mileage ones the try hard dealers will add more on because they think there is a demand which there actually isnt.
But personally is there any particular reason you want the DTM?
Because if I can make a suggestion, I mean I dont know your financial situation or if you going to trade your current car in etc.
But there is this vehicle for sale:
Audi A4 2.0T FSI Quattro S Line Special Edition 4dr
Which is seems like the better buy thou this is just based on viewing of the ad and pictures. But its the same - phantom black colour,alloys, engines, bose sound system. Roughly the same mileage. 2 owners. New tyres.new front disc and pads. The only visual differences will be front and rear bumper, front grill, larger tail pipes thou it has same exhaust system and 2 carbon fibre pieces. And of course the alcantara interior but then again some prefer leather its a lot easier to maintain and if you spill anything its a breeze to clean on the alcantara I wouldn't say the same. By no means am I trying to put you off the DTM I mean I own a sprint blue one myself and its a great car. But quite frankly had I shopped correctly the smarter move would have been the special edition s line quattro because they were the last run of the Audi A4 in that shape and Audi threw loads of extras into them. Which really makes the DTM look like a lessor car even thou there was only a limited run of them. But then again so was there for the special edition. Oh and you get fog lights on the Sline and not on the DTM if that matters.
And considering you are not mechanically minded as you said. Why not save your self £2000 for almost the same vehicle? Just a thought. So if you have the doubts about the oil pump and oil pick up you have a budget to play with considering you are prepared to spend 9.5k already.
Just to clarify about the oil pump and pick up situation the later models didn't suffer so much with this issue above. Thou there have been a members recently having the above issue. If the car is currently mechanically sound the best thing would to do is take it to a Audi dealer or a Audi specialist. Have them remove the sump and put the revised pick up pipe unless its already on there but you can only tell once the sump is off. And while you there you can get them to change the oil pump for the sake of maybe £500-£600. You should be happy motoring. Just do more frequent services on the vehicle and use decent oil fully synthetic. People tend to put these cars on a long-life service plan as it means the car only needs servicing every 2 years. Which is the worst thing one can do for this vehicle especially because it is turbo charged one should run the vehicle on at least 1 year oil/oil filter change unless your pocket can stretch to do it every 6 months thou again depends on your mileage.
There is loads of information on this forum if you need any help or assistance because 90% of the time someone has already suffered the same issue were it be a oil sensor to the rear brakes making a noise etc.
Hope this helps.
I think they are overpriced though to be honest. Whats your opinion? I have been looking for a good few months for one. I remember last year cars with same mileage were going for around 8k. Also how can I stop the oilpick up and oil pump problems?
. I do like the special edition, but its the dtm and all the refinements such as the bumper fins or whatever they are make it stand out.
