S line or Standard a4?
 

Hey guys im new and would firstly like to say hi to the forum!
Hopefully ive come to the right place and im hoping someone could help me out
Im currently looking into buying an a4 1.9 tdi 115 bhp. Ive found 2 that i am quite interested in but not sure which one to go for. 1 is a 2005 reg 1.9 tdi S Line with 86000m cloth interior with built in sat nav and the other is an 57 reg 1.9 tdi with 106k miles and full leather interior, parking sensors and standard 07 double din head unit. Both of these cars are the same price at 6.5k quite high but which do you think is worth going for if any?
