the only trouble is at £35k sort of pricing you are up against new kids on the block like a brand new RS Focus, or a newer 911, lots of cars abound at 35k. does a collector want a car with 155k on it? no, and would someone want to trackday it perhaps, again with an eye on engine life. its a fine car, with higher end mileage, so the market will be slower i guess to jump in. if the seller can wait, he may get a decent return.
or Zingers might just re-evaluate a standard unit to £30k and step in perhaps?
