Currently I have an E46 M3, and AP1 S2000, and an F31 330i Touring (daily duty)
The M3 is getting new wheels this spring, as well as getting odds and ends fixed up from age.
The S2000 will be undergoing some maintenance, but I have to pull the suspension and reset preload on all the coil overs due to me being dumb when I first installed them when I was younger.
The 330i is getting creature comfort retrofits. I just retrofitted the heated steering wheel coding/switch, and next will be an antenna and coding to run an OEM Apple CarPlay connection.
