i have just read this post and i am actually quite taken back with how rude some people have been , all this guy wanted to know is if it was worth his while in been an owner driver , admitting he knew nothing about what to do as it was his first time in looking into this side of the business , a bit of encouragement or an explanation on why it would be a better idea to wait or stay put in the business he is in would have been better than silly remarks asking if it is a joke post , remember you where once in his shoes!
The question has been asked since Noah was given a couple of pets, the answer hasn’t been found yet. So not to be rude or patronising to Danny, he needs to do some more homework, lots of it, read a lot, listen a lot and make a lot of notes. Rob K has often stuck to his line about Mars Bars, unfortunately he has been proved correct more than once, there are some threads on this forum that will explain, some are still members, some crawled back under their rocks.
In the last 20 or so posts there are many operators who are finding things difficult, fuel, wages, breakdowns, interest rates, lack of work and rising insurance premiums, as well as the fact that the digital tachograph has been used since 2006 whilst the analogue unit has been in our cabs for over 30 years and even longer in Germany. Added to this, the WTD/RTD, road speed limiters, financial standing and much better enforcement and public enquiry have tightened the entry requirements into this industry.
Other posts have mentioned taking a risk and the big boys didn’t start with 600 vehicles. No they didn’t, but they had a much more flexible understanding of the regulations. At risk of being controversial I would suggest that most operators who run a multifaceted organisation did not get there by pure luck or by having shinier trucks than the bloke down the road. It may have helped them recruit the better driver, but what is better? the bloke who could squeeze in an extra Glasgow in the week or the one who washed his lorry every day?
I am interested how the new start with the Mercedes is going to cope with a 24k invoice that wont be paid in his first year of trading. I did it in better times and personal circumstances changed my views. Do I regret it? Hell No, would I do it again? Not in this financial climate, especially not when relying on the trade press and 2nd hand sub contracting. Type European Transport Company into Google and see who comes up, they will load Danny to anywhere he likes, they will even load him back, until Danny gets an invitation from his bank manager to have a chat. The freight forwarders wont worry, they will just wait for the next owner operator to call them. There are dozens of companies that will offer you work, there are dozens of hauliers doing it for nothing, why? simply to keep the payments up.
His boss has a special rate for a hire truck of £400 per week, that is £1733.34 a month or almost £21,000 or you could buy this DAF for half that money and still earn the same amount.

Anyone wishing to become an owner driver, do yourself a favour, follow in Pauls (Repton) footsteps, study the opportunities in your area, talk to a few people who are still doing that work, get some experience of the type of loads you want to carry and do even more sums. Do me a favour and buy a diary, write down every job, including mileage, write down RDC delays and accidents. Make a list of every breakdown, every parking ticket, every puncture or tyre replacement, every gallon of oil and every night out allowance you claim off your boss. Add this to the £500 per week wages which will actually cost him more than that with his Ni contributions.

Dont forget to write down all the fuel & oil you put in over the year, the days you cannot work because the truck is in for its 6 week inspection, a week or so for repair, MOT and we still haven’t looked at a trailer or trailer hire. I think ShuttleSpanker mentioned in another post what the big container companies do to you. I certainly know what the trailer hire companies do.
Come back next June and tell us if it is a viable proposition, there is no rush, after all in 20 years you will be a millionaire 
Good Luck. Me, I would stick to the 500quid for now.
