I was in a similar boat, I have a VH Wagon a VX Wagon and I had an AU3 XR8. Sold the XR8 as it was the least practical at the time and bought a new Fiesta
I though about selling all or some or what ever but I kept the VX as it does the highway trips better than most, its got a huge boot and its faster than the Fiesta, kept the VH on club rego so i only use it for shows or club events or the weekend test drive.
The Fiesta's great, its black, chucked on black 17in rims, black tint, zetec kit and really its only good for short trips or around town
Anyway I am selling my Fiesta after 10 months of owning it as the reason i bought it (travelling 150km per day for work) changed, and now i only travel 8km to work
so my plan is to either put full rego on the VH or sell the VH and buy a decent fast V8 and drive that 8km to work each day
p.s. i looked at every sub $20k hatch out there and the Fiesta won hands down, faster, bigger motor, bigger drivers compartment, best handling, best driver feel, looks decent for a hatch, and was one of the cheapest at $15300 driveaway and one of the best on fuel usage
the new WZ's are only a 1.5 with less power and if you want new the WT 1.6l are in runout for $14500 or you can buy mine for $12k only 10 months old with 13,000km...haha
