Potential Superb buyer

[AUSL]

Hey everyone, I'm in the market for a second car and am considering a Superb. I had my eye on a VRs but the harder suspension along with the fact that my wife is pregnant had me looking toward the Superb. I'm in Brisbane and there appears to be several used sedans in Ambition and Elegance trim, but with the 118 engine. Everything I've read suggests that the diesel 125 would be better in the heavier Superb. Is this correct? I'm hoping to test drive the cars in sedan and wagon form on the weekend.

I could use some pointers from all you knowledgeable Superb owners. How do you think the smaller petrol engine would cope on the car? Should I keep looking for a 125tdi? The wagon shape I like appears to be in Ambition trim. What sort of upgrades do the Elegance trim bring?

Thanks for your help.
