Had my Slk350 for 18 months now and as you do spent a bit of money on modifications I was wondering what was your best upgrade without breaking the bank?
I have added
A smart top - good and convenient
Sprintbooster - made a real difference on responsiveness
K&N air filter- further responsiveness improvement and sound
Had front exhaust boxes removed - good and cheap way to get better sound without paying for sports box and not effect emissions
Lastly one I would recommend is having an EDT treatment which has made marked difference in smoothness,free revving and responsiveness .
You will see a common thread on improving responsiveness as always felt whilst 300 bhp never really felt like it ,but now feel without buying 55 that my Slk is real fun . Welcome your thoughts
