Yea you are entitled to your opinion and you can get a TS for five hundred quid or you can pay for a car that has been looked after by an enthusiast who didn't prioritise the running costs ..
if you look at very old posts on this forum it was all about "where can I find a garage/grubby little man that can fix my ashtray lid"? to today's.. "How do I rip the suspension apart on my drive"?
Tot up things like rear suspension rebuilds .. belts .. and the numerous other common niggley faults like thermostats and wet foot wells and you can see what the car is really worth.. there is no book price ..
mileage means bugger all on anything over ten years old .. most E types have been to the moon and back.. it's all about maintenance.
these cars are in no man's land between being a low value old car and a classic .. all good cars go through it..prices are rising at the moment..
many British and Italian cars reached classic status.. well there are no British cars any more..
not long ago you could buy a running MGB for a few hundred quid ..prices are now anything from a grand for a wreck to about ten grand.. have you seen the price of original mini's these days?? there is no book price .. the market will decide..
"Practical classics price guide" Which is pretty much the definitive UK price guide for classics .. google it ...
puts a V6 GTV at 750 to 3750.. condition 3 to condition 1..five grand for an original minter.. more for extra special concours with good mods.. which I think is about right..
when I sell my car I'm going to interview prospective buyers and they will have to pass a written and practical examination
