My 33 year old Miata had been garaged for its first 30 years in Maryland, but the blazing Florida sun, without any coverage, paid a toll with the weatherstrip seals on both doors. Checked out the internet and videos demonstrated that swapping the deteriorated strips out could be pretty simple...and it was a true "walk in the park". Took me about an hour to replace both. Couldn't be happier with VIPIH for the quality and cost. I'll look to them for any replacement parts in the future.
