besides as soon as you start sticking milage on the car you knacker it's resale valuehave a look around as there's some real bargains to be had - picked up my 172 last week for £3.5k with FRSH and 65k milesjust done the timing belt service and a few other bits and bobs, will be looking to get rid in a few weeks once my 205 gets rebuilt if you are interested...Personally, I'd rather have a 172 with average miles (or just below) than one that has only covered 10-20k tbh. Cars that are used daily and maintained as they should be, are more reliable than cars that are sat about for long periods of time.
