I'm with Adrian for the Alto at £280 fully comp but that is the most expensive car for me. Had little choice based on the chassis number and such a rare model. Your HA11s looks great
My skyline has been sitting for about 7 years too Fully rebuilt now, bare metal spray, engine completed stripped and rebuilt. Sitting around 450ish but not done yet. Just getting the Alto complete next week (well, my mates garage are!) then its onto the Skyline which shouldn't be long at all, no spark getting through but not looked at.
Driveshaft's fitted and feels great, so much better.
While in, also got a FCD fitted as well as a new boost controller (cant remember the type, still manual but better for holding boost). Speedo now reads in MPH, the Jimny converter I found done the trick I just need to get the odometer changed which should be easy enough.
