I am currently 16 years old, 6'3 and around 200 pounds. I've been trying to buy a used Porsche Boxster/Boxster S Convertible 2000-2003. The only concern l have over this is my height, l have been in many sports cars that l have trouble with my height by my head sticking over the top.. Such as the BMW 3 series convertible, and Mercedes SLK convertible. l do not ever sit straight up when i'm driving... l usually slouch down.. But if l was to slouch would my legs be riding up on the steering wheel? Porsche really catches my interest so l was wondering if there was anyone that could help me or could post previous experiences.. Thanks

l am also 6'3 & have owned a number of sports cars that were probably too small for me, but frankly, put the biggest ever smiles on my face.
Notably the honda s2000, lotus elise 111s & the porsche boxster s (currently own a late 01 model).
regarding the boxster s & ur question in particular - yes u can get away with slouching a bit & u should have plenty of room for ur legs still. however, whilst the causes of my current back problems cannot be exactly confirmed, l am pretty sure it may in part be due to squeezing myself into tiny sportscars for too long!
If budget allows, go for the 911 - it is slightly bigger. It is not mid-engined, but a fantastic car.. Do not know whether it is quite what u r looking for, but also give the Nissan 350Z a chance / testdrive. great bang for buck, & is (strangely unlike other japanese cars) well suited for taller drivers.

l have driven a 98 Boxster, which is the same as the 2000-2003 versions.
l am 6 foot tall & 190 pounds & l had lots of room & sat comfortably.

l have driven over 200 cars & many sportscars like the 350z, Mazda RX-8, Audi TT, Mercedes SL55 AMG, Chevy Corvette, & more.
When l drove the Porsche Boxster, l knew that l would one day buy a Porsche. It was the most fun l had in a car.

In the rain, it is very slippery since it is RWD & the tires were not all season tires.
And the one l drove had a broken convertible top that did not open. l do not think that is a common problem, but u should make sure u close it & open it properly so it does not break.
