VAUXHALL travelled south in optimistic mood after a draw at high-riding Kettering in midweek.
But their hopes of returning to Merseyside with another Nationwide North point were dashed just six minutes from time as home defender Farmer headed in at the far post following a corner.
Borough's Murphy hit a first-time volley well wide from a decent position in the first serious action of the match. Then Jephcott headed over before the hosts took a 27th-minute lead from their first corner. Motors keeper Dittmer only partially cleared the danger and Wilkin headed the ball back across goal where Collins was on hand to convert from close range.
But it took the Motor men just seven minutes to draw level as Nesbitt hit a fierce drive from outside the area beyond the rooted Acton in the Nuneaton goal, with the help of a deflection, for his first goal of the season. Both sides went close before the break with Cumiskey having his goal-bound effort blocked after unseating two defenders, while Dittmer did well to smother Oddy's crisp, low drive at the near post.
It wasn't until the 66th minute that Dittmer was called upon again to deny Noon, while Lawton fired over at the other end. Then, on 84 minutes, the hosts grabbed the decisive goal from another corner, which was headed on to scorer Farmer by Murphy. This was the signal for Motors to throw caution to the wind but apart from one Olsen header, that drifted just wide of the far post, there was little threat posed to the solid home defence.
