Home link button at the top can be removed.

Needs info on how it works, who you are, full and proper contact details incl a form, better contrast, 404 page, xml sitemap.

Change the 3 frame slider with a simple list for better message performance.

Clicking on Chat with Advisor just shows a phone number and email address. Just have these displayed by default and make the phone number ringable from mobile devices. <a href="tel:+353871004608">087-1004608</a>

Could do with feedback from customers.

SEO
Remove meta keywords entirely: as is you are spamming keywords which has the only potential result of getting a Bing penalty. Otherwise this tag is completely useless and only has negative potential which is in play for your site.

Car Request forms need work:
Make and model could be predefined in the dropdowns with some script pulling down the models for each make.
Min year is 2008 which is restrictively recent.
Back Next buttons need to be formatted better for spacing, positions and sizes; eg. default action button should be bigger, more separate, better colour...
Trade-in form needs clearer skip function treated more prominently as it's a bit lost at the bottom.
5 days is a long time to wait for a result. Are there existing listings to pull info from? Users would much prefer some instant results.
The 'success' page for the forms gives me 'Sorry, an error has occurred. Please try again. If the problem persists, please let us know.' which means it seems to be broken.

How do you make money off this? /curious
