The 998 is a high maintenance and high repair cost (without warranty) engine compared to the 1330. I bought a used 2012 RSS with 2000+ miles on it, the dealership said the previous owner upgraded to the F3. Within two weeks of owning it, I had the check transmission scroll across the screen. Luckily the previous owner had bought the extended warranty to 2016 and I was able to add another year to last till 2017. I just got a F3S last month. I drive it 140 miles round trip to work and back and already put 1000+ miles in less than a month. The wife drives the RSS now, but I've never regretted owning a spyder. I do remember asking myself why is there so many spyders with low mileage up for sale, but I ignored my inner thoughts and still got one. I had a friend sell his 2012 RSS with low mileage because his wife was pregnant. I think some people buy it and it's not for them.
