After having a few cars too low for my Rhino ramps I've been using for 15+ years, I broke down and bought the
2 piece super lightweight Race Ramps for $300. You can't build a better, or lighter ramp with a long, low angle approach. It is worth the extra money to buy the best tool for the job, when it takes the drama out of a simple oil change. etc. The more you use them the cheaper they seem, when it makes it so easy.
