Hello all, I am looking at the Octavia 1.4 petrol engine and have noticed that they at least do a 122 BHP and a 138 BHP and also possibly a 148 BHP?   How can you tell which one by looking?  I would rather not have to trust the dealer/seller on their word.  Is there a marking somewhere, a different engine design or cover?   Can I check by entering the VIN number somewhere?   Many thanks!   Chris
