Advice Please? Audi A5 218 or 282 (thinking Superchip)

[mbc0]

Hi, 

I am looking to buy an Audi A5 (2018ish) 

There are quite a lot to choose from if I go for a 218BHP Model but the 282BHP models are expensive and like hens teeth! 

I cannot see any difference between the cars except the BHP and with Superchips offering 300BHP for £300 I have found myself in this dilemma! 

Can anyone offer any advice please? is there something else I am missing between the two models?

Many Thanks in advance!

Has anyone used a superchip in a 218 V6?
