I guess I would answer when its not fun anymore or cost effective.With the high cost of auto insurance,fuel and registration I would rather spend time and money doing some repairs on my old Benz,rather than have a car note.When its time to have some real fun and some speed I break out the other German car (Can I get a smile HITMAN X ?),but come Monday morning it back to old faithful,my 85 300sd.
