After 10 months of ownership...SHOULD I EXCHANGE IT?

[batshapedheart]

I have a 2002 base Tiptronic Boxster that i acquired on December of las year.
2 months after buying it had a problem with the coolant tank ($600) and not even a month after that I had to change all brakes along with the rear rotors ($900). a week after I had to change the rear tires ($400).
A month ago the AOS failed and I had to take care for a vacuum leak on the secondary air injection system (1388) so that two days later the battery would die on me ($150)
Ultimately it is my fault as I didnt know anything about car and didnt assess the state of the car.
After experiencing the pleasure that it is to drive a car with such great handling, I realize what this very forum has taught me: It is better to wait and buy the S manual version.
The dealer told me that soon i will have to change the coolant tank because it has some minor bleeding and I know i will have to buy the front rotors too.
Now that I'm aware of this forum and the value of a proper PPI and the common issues the Boxster is prone to; I'm pondering about exchanging my base for an S with manual transmission.
Thoughts?

I would appreciate the input of this community
