Yes, 20/20 hindsight is wonderful!
I also wish I still had the 1963 Lotus-Cortina which I bought to be built into a rally car in 1966. It was bought for £450 and still had the A=frame rear suspension which we removed and fitted 'GT-type' export rear leaf springs.
One other car I wish I still had would be the 1973 Capri 3000GXL which I bought direct from Ford in 1974 when my son was a few months old. In its day it was a very quick car and very reliable. As a long distance fast motorway car it was great. Eventually I sold it and bought an 18-month-old Jaguar XJ6 4.2 Auto.
I'd love a mk1 capri. I'd whack an LS3 in it.
I always wondered why the Capri 3-litre was not used for rallying more. With an RS3100 engine it would have been great.
When I had mine I was rallying in Datsun 240Z's. We did a sort of 'back-to-back' test with mine against a 240Z which had some suspension and braking mods, as had my Capri, and there really was nothing in it in the twisty lanes. The Capri seemed to have better brakes (competition pads/linings) than the 'Z'.
Now I wish I had bought a works rally replica 240Z which I was offered in about 2000 for £13,000.
