I have done the same mate, getting a second car to share the mileage...also had to keep it Italian.
a 98 GTV Lusso with a sunroof , 150 ponies and revtastic...bought for pennies, but I did a lot of work ! cambelt ,water pump, thermostat, lower wishbones, made and fitted new copper brake lines ( a steep learning curve for sure) from the compensator back wards, full service with oil, filters and fluids, fixed the non working sunroof, repaired the non working drivers seat relaease catch, new rear suspension bushes, fitted teledials with 10mm spacers, refurbed rear calipers and fitted new flexi hoses, fixed battery drain issue ( incorrectly fitted aftermarket radio) sorted airbag warning light ( solderd connections under seats) fixed wonky idle (clean ICV) replaced lower fogs, removed and re-sprayed mirror bases and replaced and re-sprayed broken N/S mirror...fitted new battery and bracket from a breaker...painted calipers and added decals, changed brake pads all round..cleaned all the soft touch crap of the dash and interior and fixed door card tweeters that had fallen inside and gave the whole car a thorough valet.
it was a hell of a project and took me about a month from sart to finish, but I really enjoyed doing the work...
well done finding that sport bumper...look forward to seeing that fitted..any chance you might sell the old one?
latest pics of the GT as well, have changed caliper colour from black to red ( at the front) and fitted a Novitec strut brace as well as having the uppers polybushed, and just did an oil service yesterday, will have to get the door card off this week sometime to adjust the O/S window.
the two of them offer completely different driving experiences and although the litte GTV is 100 or so ponies and a heap of torque less than the blackie its fun winding the revs up, the TS sounds fab for a 4 pot and I am really enjoying the local B roads , I am sure your little 500 offers a similar vibe, she looks fab mate, a really nice addition to the fleet...
we should meeet up in our petrol cars soon..
