BUT, not much. As far as I know (having driven Model Ss for 7 years) there simply is not any maintenance. Other than windshield wipers and fluid, I've done nothing. Not even cleaned out the carburetor. Don't know what "repairs" would be required for an S either, unless you're fixing rock dings, and they happen even when new. And since you're saving all that money, you should be able to afford a few MINOR repairs. There isn't even brake maintenance or repair, as it uses regen so much.
I tend to agree that what you'll be looking at is the beautiful curves of an S or the, uh, boxy curves of a Bolt.
I'd like to see a list of all the MAINTENANCE and REPAIRS a $30K S will need as compared to a Bolt.
