I just bought a similar 182
You sound like me!
Mine was already pretty good, in fact somebody has obviously spent money on the interior as it’s pretty much perfect.
However l soon found myself spending money!
I got a few minor dents removed, sourced a pristine carpet set (the heel pad was a bit worn on mine) replaced various under bonnet plastic parts, fitted new fog light surrounds, restored the headlamps (although they were hardly bad) got one of the Torino’s restored due to a rim dent, waxoyled underneath, and sundry other little jobs.
Fortunately l only spent £600 and l got £200 for the BGM gear shifter plus £40 for the unfathomable stereo.
Next week it’s going on for a clutch, gearbox overhaul, cam belt and water pump etc.
I guess it’s for the love of cars really as l don’t suppose l will get my money back.
Your number plate is similar to mine as well.
