Voytek Kowalczyk in particular made this process really painless. I had quotes put out in the market to over a dozen brokers (for this company car lease). There was only one quote that came in cheaper than Select but it came eight days too late (after I signed the Select papers off). On detailed examination it turned out to be £97 cheaper over three years instead of the £535 that appeared initially. This is because even if their monthly charge was £15 cheaper, the initial payment was £428 higher - assuming zero interest acrual on the £428.
Voytek is a great communicator and, though clearly busy, keep me posted on the progress. The experience so far has been great. Will return to this review when I renew in three years, to state how that has been.
