I have two sets of ramps, one set of normal metal ramps, and one plastic set of low profile “Chinese Walmart” ramps. The plastic ones from Walmart work just fine. You’re only going to use them for the front end of a passenger car, not hold the full weight of a two ton truck.
Of course, whenever you use ramps of any kind, whether they be fancy expensive ones or cheap plastic ones, I recommend you place jack stands under the car for extra protection.
Shop around at your local auto parts stores and Walmart/K-Mart type stores. I am sure you can find some low profile ramps that will work just fine, and if you don’t already have some, get some jack stands for extra protection.
