Insurance, on a second car????

I will PM anyone with the details for my trade insurance as there's discount to have for both myself and a new customer quoting my trader's number

My insurance is as follow

30 y/o Man rented house (some reason this effect's your insurance)
part time trader / full time job (minimum 6 car's a year)
I can drive anything upto 7.5t including a car transporter with upto 2 cars
anything upto 8 seats
I can't drive for social or pleasure imports or motor homes
my current limits £5,000 max payout (they say if I claim for a £6,500 car I'll be covered but they will only pay out £5,000) this is something I haven't tried as I don't drive car's that expensive
I'm covered third party fire and theft only

obviously the downfall to trade insurance is no windscreen cover or breakdown cover (I get my separately from asda for only £10 a month)

I'm paying less than £50 a month but have been with them a few years now, originaly when I took the policy out it was £100 more for trader's than it was for a 2.0 omega

try trade wise
its who im with
