I'm looking at a friends 66 Lemans Convert to possibly buy. The car looks great and the body has no visible flaws but the trunk does have a small amount of rust in the front right corner. Is this a huge deal? Also, the 326 is original and never rebuilt. It runs strong but does burn about a quart of oil after a casual summer of driving. Big deal? Comestically the car looks great-1 repaint in 1992 and no bubbles or cracks on the body. Also, since it has a one zone system on the drum brakes I was wondering the cost to split the power brakes to two zone. Thanks for the advice.
