It’s a car that can be worth money if time and effort is put into it. I think the general consensus is that the Ph1 is going to be a good investment. I think I spent about £1500 putting mine back in a drivable condition when I bought it back in 2020 and that was cambelt, dephaser, all new brakes all around, spark plugs, coil pack, HT leads and an oil change. I then spent more making it nice with the original wheels, new suspension, bushes, wheel bearings…then ITBs.
Quick check is to look behind the rear door cards and see the inner sills, if it’s just orange from a light surface coating then it’s generally good, if there are holes expect to put new sills on.
