Dinan is a tuner company for BMWs, if you spend enough and get enough "Dinan points" they'll let you buy a badge. Car is probably modified quite a bit.
The SMG is the clutchless manual transmissions most of these cars came with. 6 speed regular manual is a rare option.
These cars might sell for ~$40k now, but they were $120k new, meaning they have the maintenance costs of a $120k car. Front brake job will easily run you $1000 for example.
