i have a related question.
my driveway has two strips of hard material (red concrete?) with grass in
the middle. id love it if i could the last 20 feet or so paved over so i
could work on my car outside. any tips for what to ask for for a
contractor, or tips on finding one? if this will cost more than $10K forget
it.
the original driveway was built in 1923 and it about 35 feet long- runs
right next to the house on one side for about 20 feet.
in the summer i can put a jack on the dirt/grass, but im not brave enough to
crawl underneath with jack stands on just dirt.
anyone done this? advice? thanks,
