Purchase: Laguna ll vs. A4

Hi people, I need urgent help with these cars. I probably have to buy a new one next week. To be available: Renault Laguna Grandtour 1.9 dCi Dynamique, Kombi 62.500 km, 88 kW (120 hp), EZ: 04/03, silver-metallic, 4/5 doors, diesel, automatic climate control, ABS, stability control, central locking, electric immobilizer, leather equipment, light metal rims, seat heating, electric window lifter, warranty, rev indicator, flank protection, pre-equipment for navigation, remote control f For ZV. .. The car had two owners which deterred me a little bit at 62tkm FOR 12,95€ the vehicle is very handy. ps: what does flank protection mean?? the 2: Audi a4 bj:02 2,4L 170PS V6 with S-line sportpacket 114,000tkm run. 14,90€ 1.My questions are, how are the engines of these two vehicles regarding the run kilometers? 2.Is the Laguna a safe car ? reliable car or does it need much repair? Does the engine pull well? how fast to 100kmh and how is the 3.Is the equipment in front of the Audi ok??? So I think that was all, personally it attracts me more to the Laguna, because I just have an a4 and for it must spend a lot of raparatur cost. thank you in advance
