Former 182 owner here.
Pros:
will give most other cars on the road a pasting, and give all but the most boost-happy japanese cars a good go. Generally great fun to drive.
handles well in all conditions and can cope with snow (i had michelin PE2’s and rated them very highly)
reasonably economical if you drive like miss daisy and VED isn’t outrageous.
cons:
dont bother if you like a solidly built cabin, rattles will drive you bananas
not cheap to eke out big hp gains (but tbh if you want that then look elsewhere anyway)
insurance is rising on them as they are now cheap enough to be owned by people who like rearranging roadside furniture
older examples can cost lots of money to repair – dephaser mentioned ^ is coming in at a grands worth of work to fix.
I sold my 182 earlier this year and got a 200 and dont regret it, but as a fun car the 182 is a good option. If you’re after pace then buy one and strip all the weight out of it, its the easiest way to free up bhp on them.
