I absolutely understand that rodents are problems for many cars. That doesn't mean that we must live with this. As a retired product designer, I know that there are professionals with the backing of capable manufacturers that can come up with solutions, especially if the kits are customized to particular models. I would gladly pay $300 and probably more if I knew that the solution was robust. I don't have a garage, and as Teslas come down in price, ungaraged Teslas will become common. People are spending thousands of dollars to fix rodent damage. This problem deserves a robust solution.Wow, I appreciate your pain but pack rats, squirrels, mice, etc... get into ALL cars regardless of make and cause extensive damage. Easiest solution is to park your car in a well kept garage. Lot's of people around here (who park outside) leave their hoods up at night, put lights under the hoods, etc... to combat the problem.
Anyway, good luck!
