Sounds too pricey to me.Atco is a good make, but it will have seen service in 6 years possibly.
Have a good look round in garden stores and on the net before you buy.
Altho it is too much for a second hand mower. something to think about tho, is that a good Atco could last you a lifetime, so if it hasnt seen much use, a bit of haggling could bag you a reliable and trusty machine.
went back today and did haggle i pointed out that she told me that i was the only phone call she had so this showed that the price was to high i gave her my final offer of �100 pounds and she accepted it so i am now the proud owner of the atco
