Sharon , we`ve had our vectra for a year having had a 1.8 before. much better car the 2.0 , sits at 60 in 5th on the flat on motorways etc but needs to be dropped down to 4th for inclines. Clutches good and engine willing , we get 25 mpg towing. Just one thing suggest you get yours weighed on a weighbridge as there are discrepencies from handbook / vauxhall litrature. ours is 1405kgs , CDX trim should be about the same , also watch max tow weight as it does vary from year to year. Generally I like ours (apart from fidily mirrors)Changing because new van is heavier so need better max tow weight.
Will have roof bars adaptors and bulldog stabiliser to sell now as will not fit /not needed etc , so if you know anybody who may be looking for said items wants them let me know.
any other queries this is the place to ask.
Happy Caravanning. Rgds Pip
