Hi nom.... With that kind of money to spend you should be able to find something very special. Bide your time and wait for the right thing to come along, cos every now and again one comes up in mint condition for around half of your budget. Welcome to the forum!
Building the 'Mark II' fastback Rapier ('Arrocuda').
Tim is right,in todays market you should be able to pick up a very nice Rapier or Alpine Fastback for around £3000. With a budget of £6000 then an immaculate H120 is on the cards. as Tim says keep watching Flea bay & all the classic car sales web sites because something may turn up.
Yes, they do come up from time to time & yes, with 6k to spend - & you won't have to spend as much as that - to get a very very good one. A member in the SW found an excellent H120 down in Kent recently and he's delighted with it. Hang on in there
