IMO you prolly have a bad starter. Any color smoke when describing electrical issues is BAD. If your shop offers you the option, go with a rebuilt, or remanufactured (same thing) starter. Just a good as new,(but cheaper) and with a car that old it will prolly be the last one it sees anyway. If you need to have it towed in, (because it won't start) they will prolly charge you for a "no start diagnosis fee". But most shops will waive that charge (incorporate it into the price of a new starter and installation) if you have them do the work. Don't let them upsell you on a "Gold" or "Lifetime" starter, a basic rebuilt will be fine for your needs............E
