Eo’s buy Tdi or gasoline??Help Where do I get the cheap….

Hello dear Eo’s friends and drivers Have a question for you …I have the opportunity to test an Eo’s 150 Ps on Wednesday 14.06.2006. I’m currently driving a Vw Polo Facelift Tdi and can’t decide now what to buy for an engine at the Eo’s. TDI 140 gasoline 150 or 200 Ps?? My problem is if I take the 150 or 200 Ps engine I have the double fuel consumption as I currently have.Polo consumption approx 4.5 – 5.5 liters diesel. N and I would like to know what experience you have gained what the consumption of both models is???? And where do I get the best new Eos ???Where did you buy the ??Vw factory pick up ?? dealer ??? Internet??? Would I be really happy if you could help me there. Thanks Sladdi
