You should be fine. The car isn’t tuned, and your’re not pushing it crazy.
Mine is auto and I don’t use the paddle shifters. In the USA, out west, yes I cruise the same way…about 80-85ish with a minute or two up near 3 figures but I am planning to drive in Canada, the limits are low (55-60) and if caught going 25+ miles over speed limit, car gets impounded for 7 days, costs several thousand dollars…I agree with Rspin23. When I got out the Navy last year. I drove home from Washington state to Texas in 4 days solo. It was a nice drive going through I-5 then on to I-10. Some areas I pushed it to make up time from sleeping. Other than that I was cruising around 85ish. If you plan on spirited driving. I would recommend opening up the rpms through 4th and 6th before cruising into 7th. Especially since you have low mileage.
