I did like the e28, but it had it’s time. Was in good to excellent condition when I got it 6 years ago, but had a few things cosmetic and mechanical that were starting to go and not worth fixing. We fell out of love a bit over the years. I would love to get an e28 M5 one day (e28 needs to be stick I think to properly enjoy it).
e38 (fingers crossed) everything seems working (87k mi on it) and while I still have the W115 Benz for fun, girlfriend insisted on a car with AC, proper seatbelts and airbags. 98 seemed like a good compromise - new enough to be modern, but old enough to be unique.
Guy I got it from (who imported from Cali) is a BMW nut. Has a new M5, and previously had an e28 B7 Alpina, e34 Alpina, 850csi, e30 convertible among others…
