*Imagine a mildly patronising voice*
For me all that matters is total cost as indicated by roadrider and pansmiker, if your doing PCP because you think you will walk away from the bike then thats fine, just dont think your not paying more for that. I get mildly frustrated by the focus on low monthly payments (MCN regularly do this, having special features for bikes you can have under £100 pm etc). This means nothing unless you have worked out the total cost and compared it. I've seen a slightly smaller number of threads where people then dont know what to do when forced a) to lose the car, or b) are in finance not PCP and then have negative equity and are stuck.
I've lost count of the number of threads (mostly on car forums) where someone thinks they are quids in as they have managed to buy a new car and keep their payments the same or make them lower, without mention of how much longer they will be paying, what the rate is, and the size of the balloon payment that will inevitably force their hand.
The funny thing is that its a vicious cycle, if everyone is attracted by PCP and more go down this route, the residuals of the bikes will be affected and then the next PCP will have a slightly higher balloon payment to counter for the softening residuals (thats a generalisation, but a logical conclusion).
Not against PCP at all, but I am pro financial knowledge and education.
