Thanks for the messages of support everyone! I get to pick up the car from the shop this week, and I can't wait.
I haven't actually driven the car since last August !!!
Don't worry hubcap fans, I'm planning to keep the steel wheels & caps for special occasions! The tyres on the steel wheels were between 15 & 27(!) years old when I bought the car, so they had to go anyway. The steel wheels themselves could also do with refurbishment. It worked out cheaper to buy the bundt wheels & tyres off eBay than just buy new rubber in the short term, although the current tyres are slightly the wrong size (185/70R14 instead of 185/80R14 which I hadn't noticed) I'm slightly surprised someone didn't pull me up on that!
I'm intrigued by the aluminium steel-alike wheels - I had no idea such a thing existed Raptelan
The real downside with the alloys (for someone as lazy as me) is the amount of cleaning required!
