Rusty, stock and with over 200K. I'd love to find a decent CRX HF but this car will do for now.
I do carry a decent tool kit around and still have full interior, including the spare tire and jack.
Does the factory passenger mirror block-off plate count? I did recently replace the slipping clutch and my city driving fuel economy bumped up from the mid-upper 30s into the low 40s. I weigh 125 lbs so there's not much I can do on that front.
I don't do any P&G and very little EOC. I'll shut the engine off if I hit a familiar stoplight at a bad time.
Not much. This car's too rusty for me to spend very much time or money on. I don't know of any instrumentation that will work with the DPFI setup; otherwise, I'd love to have some instant feedback. I may hook up a vacuum gauge at some point.
